It’s no doubt, this Bombshell belongs in a calendar – she is a beauty. It’s an improved paniculata type Hydrangea, which means it produces big cone-shaped flowers. And this Hydrangea produces a ton of flowers — it will turn heads in your yard! What makes this plant special is that it combines its prolific flower production with a compact form that will fit perfectly into any yard in suburbia. So find it a sunny spot and plant, water, relax.
If you do the bare minimum of making sure your plant gets some water when it’s hot out in the summer, it will do fine and perform well for you. But to see what its fuller potential can be, here are a few other tips:
An easy way to keep weeds down around your plant, and to keep it moist with less watering is to throw a 2 inch layer of mulch around the base of the plant – basic bagged “landscape mulch” from your local garden centre will do the trick.
Hydrangeas don’t need a lot of fertilizer, but they do benefit from a shot of good all purpose fertilizer in the spring when the leaves start to sprout. A fertilizer with a higher middle number (e.g. 15-30-15 or 5-10-5) will work best.
The best time to do a little trimming on your hydrangea is in early spring, just before it starts to grow again (just after you see signs of life is okay too). Removing dead flowers from the previous year is a good start. You can also cut back the top 1/3 of the woody branches.
Important tip: don’t trim after June 1 – you might cut off the new flower buds if you do!
